Proxy gurus please help

Dear BHW community,

I am in need of your direction and advices with my situation. Any opinion is much appreciated.

I frequently buy from USA based merchants like Macy's, kohls, sephora etc but I dont live in USA myself.
I have USA shipping address, USA bank issued card, USA paypal account and I was using NordVPN to do my online shopping.

But recently merchants are canceling my orders and my accounts are being flagged. They are detecting VPN
My devices geolocation, VPN IP and timeone are set to match my billing address.
I tried NordVPN dedicated IP, obfuscated IPs nothing worked. There was no DNS leak either.

Can you tell me how I can shop from those websites?
I want to try residential proxies. can anyone recommend a good provider?
Or any advise how I can shop like a real local user and not like someone using a proxy from another country?

Best regards

u might want to try out some mobile proxies https://www.blackhatworld.com/forums/proxies-for-sale.112/

Don't use VPN anymore for purchase, it will get flagged

Find a reliable Static Resi IP provider.

if you are someone that is usually on the road you will need a reliable static IP provider for this

Thank you for your feedback.

What else should I consider along with the static residential proxy?
Any recommendation where I can get static residential IP from the city of my billing address?
